System.ArgumentException: 'Id field is not correctly populated' - asp.net-core

Question

I am trying to implement Redis, I am sending a put request from Postman and getting error.
Controller:
[HttpPut]
[ProducesResponseType((int)HttpStatusCode.Created, Type = typeof(Brand))]
public async Task<IActionResult> Update([FromBody] Brand brand)
{
try
{
await _brandCollection.UpdateAsync(brand);
return Ok();
}
catch (Exception ex)
{
throw ex;
}
}
Error:
System.ArgumentException: 'Id field is not correctly populated'
From redis desktop manager I have confirmed that Id exists in record
Postman:
{
"Id": 1,
"Name": "Xiaomi",
"IsRegistered": "Yes",
"About": "Mobile Brand",
"Countries": [
"Pakistan",
"India",
"China"
]
}
Brand model class:
[Document(StorageType = StorageType.Json, Prefixes = new[] { "Brand" })]
public class Brand
{
[Indexed] public int Id { get; set; }
[Indexed] public string? Name { get; set; }
[Indexed] public string? IsRegistered { get; set; }
[Indexed] public string? About { get; set; }
[Indexed] public List<string>? Countries { get; set; }
}
I have injected HostedService as well in Program.cs:
builder.Services.AddHostedService<IndexCreationService>();
IndexCreationService:
public class IndexCreationService : IHostedService
{
private readonly RedisConnectionProvider _provider;
public IndexCreationService(RedisConnectionProvider provider)
{
_provider = provider;
}
public async Task StartAsync(CancellationToken cancellationToken)
{
await _provider.Connection.CreateIndexAsync(typeof(Person));
await _provider.Connection.CreateIndexAsync(typeof(Category));
await _provider.Connection.CreateIndexAsync(typeof(Brand));
}
public Task StopAsync(CancellationToken cancellationToken)
{
return Task.CompletedTask;
}
}
